Question

Q10 The length of the rectangular frame is 3 times its breadth. If the perimeter of the
frame is 164 m.
Find the length and breadth of the frame.​

Answer 1

step by step explanation:

Perimeter = 164 m

Let the breadth of rectangle = x

So, Length of Rectangle = 3 times x

= 3x

Perimeter of Rectangle = 2(l+b)

Therefore, 164 = 2(l+b)

164 = 2(3x + x)

164/2 = 3*x + x

82/3 = x + x

27.33 = 2x

27.33/2 = x

13.665 = x

So,

Length = 3x

= 3*13.665

= 40.99 = 41 m

Breadth = x

= 13.665 = 14 m
